There are 2 possible reasons for it to say there are no detailed map available. The most likely reason is that no map is selected. Press Tools, then Press Settings, then press Map and then Map Info. There should be a tick beside the name of the map installed on the satnav. If not press the map name to select it. A tick will appear at the side of the map.

The other reason is that the map may be locked. You'll need to go to My Garmin, and then Maps to get the unlock code.

To download the latest unit software visit Garmin website: www.garmin.com/webupdater
First you have to set up an account at Garmin using the serial number on your GPS. Once you do that you can download firmware update for free.
After installing WebUpdater once from the Garmin website, perform all future software updates from your computer. Simply connect your compatible Garmin device to your computer, then run WebUpdater from your computer's "Start Menu" by selecting "Start", "Programs", "Garmin", and finally "WebUpdater"
REMEMBER: It takes hours to do a complete a map update.
Unless you bought the Lifetime maps you may have to pay for current maps.

By the way, the correct Garmin approved power OR download cables are a must!!
Does this help? Let us know. Thanks.
